摘要：

Excited states in Pm-146 have been investigated through the Xe-136(N-15,5n) and the Nd-146(d,xn) compound-nucleus reactions. A level scheme extending up to 6.9 MeV of excitation energy and (I = 25HBAR) is proposed. Most of the high-spin levels are interpreted in terms of multi-particle-hole states but at medium spins octupole-phonon excitations are identified. The results are discussed and the level scheme compared with analogous states in neighbouring nuclei. Yrast configurations in Pm-146 are described by the shell-model calculation involving empirical single-particle energies and two-body interactions.
